Question
Which of the four statements below about natural selection are correct?
- Competition occurs between individuals of the same species.
- Competition occurs between individuals of different species.
- Selection can lead to evolution.
- Selection can lead to extinction.
A) 2 and 4 only B) 1, 2 and 4 only C) 1, 3 and 4 only D) 2, 3 and 4 only E) All of the above
Solution
E) All of the above
Explanation:
-
Competition does occur between individuals of the same species for resources like food, mates, and territory. This is known as intraspecific competition.
-
Competition also occurs between individuals of different species. This is known as interspecific competition. For example, different bird species might compete for the same nesting sites.
-
Selection can indeed lead to evolution. Over time, traits that improve survival and reproduction (fitness) will become more common in the population, leading to evolutionary change. This is the basic principle of natural selection.
-
Selection can also lead to extinction. If a species is unable to adapt to changing conditions or compete with other species, it may be selected against and eventually become extinct.
